Hestia is a space-ready heater & temperature measurement system developed by Mawson Rovers in Sydney. Its first mission will demonstrate a novel UTS heatsink design, aboard the Waratah Seed cubesat mission. It is due to launch on a SpaceX rocket in July 2024.
At higher temperatures, the PID loop doesn't quite reach the target temperatures.
We need to tune it to match the responsiveness of the heater when it has a big heatsink on it.
